As a result, libraries are no longer the initial point for research, and now a day even it is not considered as necessarily integral to scholars’ research work-flow. Sedwick, M (2012) is of the view that libraries now navigate inexorable turbulence in an information environment irreversibly tainted since the advent of the Internet and migration to digital formats and hence Libraries are struggling with a new flora and fauna which help users in discovering scholarly content, including search engines, social networks, and websites from scholarly societies, academic communities, publishers, and journals. Resource discovery tool not an equivalent to “Googling” something, but it is an evolved function that proposes better results for the library / information users. This latter set of content-hundreds of millions of items-can include items such as e-books, publisher or aggregator content for tens of thousands of full-text journals, content from abstracting and indexing databases, and materials housed in open-access repositories.
In addition, web-scale discovery services pre–index remotely hosted content, whether purchased or licensed by the library. Such capabilities existed, to varying degrees, in next-generation library catalogs that debuted in the mid 2000s. Such content can include library ILS records, digital collections, institutional repository content, and content from locally developed and hosted databases. Web-scale discovery services are able to index a variety of content, whether hosted locally or remotely. While the technologies underlying such services are not new, commercial vendors releasing such services, and their work and agreements with publishers and aggregators to pre-index content, is very new. Web-scale discovery services, through the view of Vaughan (2011) are combining vast repositories of content with accessible, intuitive interfaces hold the potential to greatly facilitate the research process. A single search interface which will combine all the results from library databases, catalogues, electronic resources etc are much more appealing than searching each in separate windows. For the sake of convenience of searching the resources, the integration of internet and library catalogues were in discussion for past several years.
